Can You Trade Options After Hours? Pre-Market, After-Hours, and Overnight Rules
Summary
Standard equity options trade during regular market hours only (9:30 AM - 4:00 PM ET). However, SPX index options trade nearly 24 hours on the CBOE, and select ETF options (SPY, QQQ, IWM) have extended-hours sessions at some brokers. This guide covers what's available, the liquidity and pricing risks of after-hours options, and how overnight gaps affect your positions.
Key Takeaways
Most individual stock options cannot be traded after hours. SPX options trade from 8:15 PM ET (Sunday) through 4:15 PM ET (Friday) with a brief maintenance break. Select ETF options have limited extended-hours availability. After-hours options trading has wider spreads, less liquidity, and different pricing dynamics. For most retail traders, managing overnight risk through position sizing and defined-risk strategies is more practical than after-hours trading.

Markets move 24/7 but most options trading doesn't. A major earnings announcement at 4:30 PM, a Fed decision at 2:15 PM that you couldn't react to in time, or overseas market events at 3:00 AM all create gaps that affect your options positions without giving you the ability to trade.
Standard Options Trading Hours
Regular Session: 9:30 AM - 4:00 PM Eastern Time, Monday through Friday.
This applies to:
Important: Options orders placed after 4:00 PM will not execute until the next trading day's open. Market orders placed overnight can fill at unexpected prices due to overnight gaps.
Extended Hours Options
SPX Index Options (Nearly 24-Hour Trading)
The CBOE offers Global Trading Hours (GTH) for SPX options:
This means SPX options are available roughly 23 hours per day, 5 days per week. You can react to overnight news, overseas market moves, and early morning economic data releases.
Caveats: After-hours SPX spreads are wider ($0.50-$2.00 vs. $0.10-$0.50 during regular hours), and volume is substantially lower. Large orders may not get filled at fair prices.
SPY and Select ETF Options
Some brokers offer limited extended-hours trading on major ETF options:
Availability varies by broker. Check with your specific platform for current offerings.
VIX Options
VIX options follow similar extended hours to SPX on the CBOE exchange.
Risks of After-Hours Options Trading
Wide Bid-Ask Spreads
During regular hours, a SPY ATM option might have a $0.01 spread. After hours, the same option could have a $0.10-$0.30 spread. This hidden cost makes frequent after-hours trading expensive.
Low Volume and Poor Fills
Fewer participants mean your order sits in the book longer. Market orders are dangerous because you might get filled $0.50 or more away from fair value.
Stale Pricing
Options pricing models use the underlying stock's current price, interest rates, and volatility. After hours, the underlying stock price may be moving on thin volume, and the options pricing may not accurately reflect fair value.
Managing Overnight Risk (The Practical Approach)
Since most options can't be traded after hours, managing overnight risk through position structure is more practical:
Use Defined-Risk Strategies
Spreads, iron condors, and butterflies have defined maximum losses. If news breaks overnight and the stock gaps 10%, your maximum loss is still the spread width minus the credit received. No surprises.
Size for Gaps
When holding positions overnight, assume the stock could gap 3-5% against you (normal conditions) or 10-15% (earnings, major news). Size your positions so these gap scenarios produce acceptable losses.
Close Before Binary Events
If your stock reports earnings after the close and you can't trade options after hours, close your options position before the 4:00 PM bell. Holding through an earnings announcement you can't react to is accepting a coinflip.
Use SPX for Overnight Hedging
If you hold positions in individual stocks and want overnight protection, SPX put spreads can be traded after hours (through CBOE's extended session) and provide broad market hedging.
Weekend and Holiday Risk
Options positions held over weekends face additional risk:
For sellers (positive theta): Weekends are generally favorable. You collect two days of theta without the stock trading. But if bad news breaks, Monday's gap can exceed the theta benefit.
For buyers (negative theta): Weekends cost you two days of time decay with no opportunity for the stock to move in your favor. Avoid holding long options over weekends unless you have a strong catalyst thesis for Monday.
Use OptionsPilot to monitor your portfolio's overnight risk exposure and evaluate which positions should be closed before the weekend or ahead of major events.
